Parameter (Tag) Adjustments
All tags in the RSLogix5000 Application Module program that require tuning or adjustment
during commissioning or maintenance are prefixed with a (z). These tags are referred to as
(z tags). Please review and adjust the setting of all (z tags) as required before activating
control of the drive.
The following (z tags) are of particular importance for operation of the application module;
zDLx_ControlMode – Select the positioning mode of operation. Only “Linear Posit”
and “Linear ABS” are supported in rev 110101 and 110102. Linear ABS requires the
use of a “Multi-Turn Stegmann” feedback device.
zDLx_EUperMachineRev_EU – Sets the scaling of the position targets to the
desired engineering unit. This scaling value is used to calculate the actual position
counts per the position target setpoints. All motor controlled machinery begins with
rotational motion.
If the machine is operated as rotational motion, a common form of
engineering units is degrees. There are 360degrees in 1 rotation of the
machine, therefore set this tag for 360. (1 rotation = 360º) a command of
720º will equal 2 machine rotations.
If converted to linear motion, measure the linear distance traveled for 1 final
mechanical rotation (not motor rotation, unless no gearing). This may be
entered in any units desired by the customer. The units specified here are
the units used throughout the application. All position commands will be
entered in these units.
zDLx_GearRatio – required for calculation of actual position counts to position target
in EU. Number of motor rotations per 1 final mechanical rotation of the machine.
zDLx_HomeHexigonBckup_Cnt – not supported in rev 110101 and 110102
zDLx_HomingMode – Select the operation desired for the Homing sequence.
1 = Direct 1 Sensor
2 = Direct 2 Sensors
3 = Hexigonal – not supported in rev 110101 and 110102
zDLx_PositionQty – Sets the quantity of target positions used with the “Next
Position” command.
zDLx_PositionTrgtRef_EU – Each target position to be used must have an
appropriate target position value set.
zDLx_PositionTrgtSpeed_Pct – Each target position to be used must have an
appropriate speed value set. This will determine the speed at which the move to
position for each target is completed.
